SHIP COMPRISING ENGINE Russian patent published in 2019 - IPC F17C9/02 

FIELD: vessels and other watercrafts.

SUBSTANCE: invention relates to storage of liquefied gases. Vessel containing engine comprises: first self-heating heat exchanger, which performs heat exchange of stripping gas discharged from reservoir; multi-stage compressor, which in several stages compresses the stripping gas, which is passed through the first heat exchanger after discharge from the reservoir; a first decompression device which expands one portion of the stripper gas compressed by the multi-stage compressor; a second self-heating heat exchanger which performs heat exchange of the other portion of stripping gas compressed by the multi-stage compressor, with stripping gas expanded by the first decompression device; and a second decompression device which expands the stripping gas pre-cooled by the second self-heating heat exchanger and cooled by the first self-heating heat exchanger. First self-heating heat exchanger uses a stripping gas discharged from the storage tank as a cooling agent for cooling stripping gas, which is passed through a second self-heating heat exchanger after compression by a multi-stage compressor.

EFFECT: technical result is higher efficiency of re-liquefaction with simplified maintenance and overhaul.
